CARRIAG E- -CU RTAIN FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 713,892, dated November18, 1902.

Application filed April 4,1902- Serial No. 101,433. (No model.)

To all whzmt it may concern.-

Be it known that I, HAVILAND LESTER, a citizen of the United States,residing at Binghamton, in the county of Brooms and State of New York,have invented certain new and useful Improvements in Oarriage- CurtainFasteners; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being badto the accompanying drawings, and to the figures of reference markedthereon, which form a part of this specification.

This invention relates to devices for attaching side and back curtainsto the backstays of carriages. Its object is to avoid the necessity ofattaching any part of the fastener to the curtain, so that the curtainwill adjust itself to the fastener,and therefore lie flat and not warpor wrinkle.

A further object is to provide a fastener that can be quickly and easilyoperated.-

The invention consists in a fastener comprising a pair of jaws adaptedto clamp a bead or thickened portion of the edge of the curtain andoperated by two cams rotatable by a central stem, the cams beinginclosed in a body which is firmly secured to the backstay.

In the accompanying drawings, Figure 1 is a perspective view showing myimproved fastener applied to a backstay and holding a curtain. Fig. 2 isa vertical section of the same. Fig. 3 is a similarsection with the jawsopen. Fig. 4 is a sectional view on the line 4 4, Fig. 3. Figs. 5 to 10,inclusive, are views of the separate parts of the fastener.

The lower jaw 1 is a plate of sheet metal having a preferably circularenlargement at one end to serve as a support for the body 2, which is acylindrical sheet-metal shell having a plurality of prongs 3,which passthrough slots at in the enlargement of the lower jaw and are clenched onthe under side of the backstay 5, preferably on a washer 6. Theenlargement is preferably provided with a strengthening-bead 16. Thehandle or button 7 rests on top of the body 2 and has a stem 8 whichpasses down through a central hole in the top of the body and isrotatably secured in a central hole in the lower jaw 1. The stem ispolygonal in cross-section to engage with two cam members 9 and 10, eachof which consists of a circular disk, one of whose faces is at rightangles with the axis, while the other is oblique thereto. In the centerof each disk is a polygonal hole to lit the stem.

The upper jaw is a strip of sheet metal 11, having at one end a circularportion lying between the two cams and having a central hole 15, throughwhich the stem passes rotatably. It projects through an opening 12 inthe side of the body 2, the edges of which guide the jaw in its up anddown movements. The upper jaw has an upward curve to fit over the beador thickened portion 13 of the edge of a curtain 14:.

The operation of my improved fastener is as follows: The stem is turneduntil the cams stand as shown in Fig. 3, which tilts the upper jawupward. The thickened edge of the curtain is laid between the jaws, andthe stem is then given a l1alf-revolution, which carries the cams aroundto the position shown in Fig. 2 and forces the upper jaw down upon thecurtain, the curve in the jaw fitting over the edge of the curtain, asshown. This operation can be very quickly performed, and the curtain issecurely held, adjusting itself to the fastener and lying smooth andflat.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is-

1. Afastener forcurtains and the like, consisting of a stationary jaw, amovable jaw, and two rotatable disks having parallel inclined facesbetween which the movable jaw is held.

2. Afastener for curtains and the like, consisting of a stationary jaw,a movable jaw, a stem rotatable in said jaws, and two disks each havinga surface oblique to the axis of the stem and rotatable with said stem,said movable jaw being held between said oblique surfaces.

A fastener for curtains and the like, con- 5 IOO and a movable jawhaving a circular end portion received in said body and lying betweenthe disks, said movable jaw projecting out through the opening in theside of the body.

In testimony whereof I afiix my signature in presence of two witnesses.

HAVILAND LESTER.
